This commit applies ormolu to the whole Haskell code base by running `make format`. For in-flight branches, simply merging changes from `main` will result in merge conflicts. To avoid this, update your branch using the following instructions. Replace `<format-commit>` by the hash of *this* commit. $ git checkout my-feature-branch $ git merge <format-commit>^ # and resolve conflicts normally $ make format $ git commit -a -m "reformat with ormolu" $ git merge -s ours post-ormolu https://github.com/hasura/graphql-engine-mono/pull/2404 GitOrigin-RevId: 75049f5c12f430c615eafb4c6b8e83e371e01c8e
